“…It is also used as an extracting agent in pharmaceuticals. Commonly used methods for the production of n -butyl acetate are the esterification of acetic acid with n -butanol − and trans-esterification of methyl- or ethyl-acetate with n -butanol. − Researchers have also studied the coproduction of ethyl acetate and butyl acetate. − Among these, the most practiced method is liquid-phase esterification of acetic acid with n -butanol in the presence of an acid catalyst. This reaction is reversible and exothermic.…”

Experiments are conducted in a lab-scale continuous reactive distillation column (CRDC) for the esterification of acetic acid with n-butanol to produce n-butyl acetate using a poly(o-methylene p-toluene sulfonic acid) (PTSA–POM) catalyst. A steady-state Aspen model is developed and validated using experimental data. Optimal design, using this model for data generation, to maximize conversion and purity yielded 93.4% conversion and 94.66% purity and 95.75% conversion and 95.01% purity using response surface methodology and Aspen-based optimization, respectively. The latter result is experimentally validated to yield a conversion of 94.2%, with an n-butyl acetate purity of 96.44%. Further, for the commercial-scale production of n-butyl acetate, a CRDC is designed in an energy and cost-effective manner through steady-state simulations. The proposed CRDC with PTSA–POM reduced the reboiler duty by 62.14 and 32.19% and the total annual cost by 30.51 and 36.85% compared to CRDC using Amberlyst-15 and an ionic liquid as catalysts, respectively.

The potential applicability of reactive distillation was investigated in the esterification of acetic acid with n‐butanol catalyzed by sulfated iron oxide at a stoichiometric molar ratio. Low‐cost, easily available, and reusable uncoated clay beads were used as column packing. Higher acid conversion in a shorter reaction time was achieved in the reactive distillation process in comparison to the batch process. The effects of reaction temperature, catalyst loading, packing material, and packing height on acid conversion were investigated. The Eley‐Rideal model was found to be appropriate to elaborate the reaction kinetics and resulted in a lower activation energy for the reactive distillation process compared with the batch process.

Synthesis of n-butyl acrylate by esterification of acrylic acid with n-butyl alcohol was carried out in a batch membrane reactor. Optimization and design of the experiment was accomplished by response surface methodology with Box-Behnken experimental design. The effects of different parameters like reaction temperature, catalyst concentration, molar ratio of alcohol to acid, and ratio of membrane surface to initial volume on water flux and conversion of acrylic acid were evaluated. A kinetic model for the esterification-coupled pervaporation process was developed. Kinetic parameters were estimated by a nonlinear optimization technique in the MATLAB optimization toolbox. The experimental and simulation results were applied for developing a concept to effectively conduct a pilot-scale esterificationpervaporation experiment.
